Description
The authors report a search for the anomalous production of events with multiple charged leptons in p(bar p) collisions at √s = 1.96 TeV using a data sample corresponding to an integrated luminosity of 346 pb-1 collected by the CDF II detector at the Fermilab Tevatron. The search is divided into three-lepton and four-or-more-lepton data samples. They observe six events in the three-lepton sample and zero events in the (ge)4-lepton sample. Both numbers of events are consistent with standard model background expectations. Within the framework of an R-parity violating supergravity model, the results are interpreted as mass limits on the lightest neutralino ((bar χ)10) and chargino ((bar χ)1±) particles. For one particular choice of model parameters, the limits are M((bar χ)10) > 110 GeV/c2 and M((bar χ)1±) > 203 GeV/c2 at 95% confidence level; the variation of these mass limits with model parameters is presented
